APPARATUS FOR STEFRILIZING WATE To all whom it may concern:

, Be it known that I, HENRY JACQUES Was- SELS, Comte de Frise, a subject of the Queen of the Netherlands, and a resident of Paris,

Fig. 1 the installation is represented as comprizing three ozonizers it h with the inteizlposition of two temperature-exchangers 2' 55 an e.

The ozonizers are represented in detail in Figs. 4, 5, and 6. ey present a special feature as regards the production of the electric discharge. The electro es jinsteadof being 60 formed by semicircular disks with a smooth edge are formed by a series of points k, maintained pressed between the two disks Z and m, Fig.5, fixed one to the other by means of rivets or bolts. 5

' Instead of isolated points sheet-metal sectors may be employe It is advantageous that the metal points should be such that they oxidize with difliculty.

e ozonizer is composed, as previously, of 7 a semicylindrical trough 0, of metal, provided with a jacket 11., of enamel. A g ass cover forms the top of the apparatus and supports the electrodes, which have just been described. The electric discharges take place between the 75 electrodes and the trough 0. The gas to be ozonized enters the apparatus by the orifice q and issues by the orifice 9', Fig. 6. Between the trough 0 and the jacket n a cold fluid ci-rculates.

In the apparatus as a whole the air is displaced, as shown in Fig. 1, bya pump t, which through the conduit 10 sends the ozonized air into the injector o. The water to be sterilized is carried along by the displacement of the air, 5

lowing specification.

I This invention has for its object an apparatus for the sterilization of water by means of ozone.

The apparatus is represented, by way of example, in the accompanying drawings.

I5 Figure l is a general view of an installation comprising the ozoneproducing appliances and the appliances for sterilizing the water.

Figs. 2 and 3 are detail views of a cooler or temperature-exchanger arranged between the 2 consecutive ozonizers. Figs. 4 and 5 represent, upon a larger scale, cross and longitudinal sections, respectively, through an ozonizer. Fig. 6 is a diagrammatic view'in plan of an ozonizer.

25 The ozone appliances utilized are of the type of those described in United States patent to Tindal, No. 636,868, dated November 14, 18.99, but in which some important modifications have been introduced.

3 It has been recognized that the air in becoming heated under the action of electric discharges producing ozone did not become ozonized under good conditions. In order to reduce this air. to the temperature which it should not exceed during the ozonizing proc ess, a temperature-exchanger or cooler is introduced between two consecutive ozonizers.

his temperature-exchanger is represented in etail in Figs. 2 and 3. It consists, essen- 4 tially, of an assemblage of tubes a, supportedby two transverse walls 6 b, constituting the ends of a vessel the lateral wall of which, 9, 'may be of any desired section-of circularsection, for example. The hot ozonized air enters the temperature-exchanger at 0, passes through the assemblage of tubes a, and issues by the conduit inorder to reach the following ozonizer. In the vessel g, around the assemblage of tubes, there circulates a cold fluid.

5 With this object the vessel 9 is provided with pressure, it'may be caused to pass through 9 the inner ajutage of the injector. In this manner it carries with it the air, thus relieving the air-pump and decreasing the heating of the air which this latter compresses.

What I claim, and desire to secure by Letters Patent of the United States, is-
